Ahead of launch for new discrete/integrated graphics backed by open-source Linux drivers, it can often be difficult to ascertain the level of support pre-launch given the complexity of today's GPUs, we are past the days of long monolithic patch series for new hardware enablement, and also not knowing about what features may be added for the next-generation hardware. But if latest Mesa developer comments hold, it looks like for Intel Xe2 graphics the open-source Vulkan driver at least has "most" of the code now in place...
